TY - CHAP M1 - Book, Section TI - Chapter 19. Sleep and Its Abnormalities A1 - Ropper, Allan H. A1 - Samuels, Martin A. A1 - Klein, Joshua P. PY - 2014 T2 - Adams and Victor's Principles of Neurology, 10e AB - Sleep, that familiar yet inexplicable condition of repose in which consciousness is in abeyance, is obviously not abnormal, yet it is appropriately considered in connection with abnormal phenomena because there are a number of interesting and common irregularities of sleep, some of which approach serious extremes. Furthermore, a number of neurological conditions have special types of sleep disruption as common features. The psychologic and physiologic benefits of sleep are of paramount importance, and it is increasingly recognized that disruption of sleep increases the risks for a number of medical diseases, including stroke, hypertension, and coronary disease. Everyone, of course, has had a great deal of personal experience with sleep, or lack of it, and has observed people in sleep, so it requires no special knowledge to understand something about this condition or to appreciate its importance to health and well-being.
